1.2 Riser Sea Floor packer?? (Drill Manager)
1.3 Air bag airlines replace with new 14 mm tubing and supply blanking fittings. (ARP to spec.)
1.4 Annular Preventer horizontal tensioning. Trolleys to run on drill rig platform columns. (ARP design)
1.5 Drilling ice hole melting. Permanent freeze-in rigid glycol ring (ARP design)
1.6 Fit filter to compressed air line before regulator to prevent intermittant regular operation.
2. UNDER ICE BUOYANCY
2.1 14 mm Airlines and blanking plugs.
2.2 New mooring straps. Check existing bags in Chch. (ARP to design, CRP purchase).
2.2 Mooring tubes. Through ice pipes of s.steel/polythene with bottom V pulley for rope and air line guides. Eight required. (ARP to design, CRP purchase).
2.4 Electrical 2 m long heating probes to free mooring tubes. Eight maximum. (ARP design, CRP Electrician)
2.5 Air Bags under Mud Hut. Discuss.
2.6 Filter in air line before regulator in Generator container to prevent regulator failure.
3. GAS DETECTION
3.1 Calibrate sensors (Auckland suppliers) (ARP to arrange, CRP Pay))
3.2 10/12 mm airline to replace 8 mm between glycol trap and Generator Container. Run airline in glycol loop insulated cover. (CRP Purchase)
3.3 Heat trace Glycol trap head, insulated head cover (snowfoam /velcro and canvas), heat trace and insulate 4 m of exposed air line. (ARP design, CRP Electrician)
3.4 Push in fittings to convert from existing 8 mm line. (ARP to design, CRP purchase).
3.5 Replace incompatible Y2K laptop computer for Science Lab Gas Readout and data storage. (ARP to spec.)
4. SUBMARINE VIDEO SYSTEM
4.1 Access damage to umbilical (ARP to arrange WHO pays?)
4.2 Repair/Purchase new umbilical (WHO PAYS?)
4.3 Normal maintenance of equipment (ARP, VUW MWksp)
4.4 Umbilical - guide wire separators (ARP design, CRP?).
4.5 Repair/Replace B&W Drill Floor Monitor and environmental enclosure (CRP).
4.6 Purchase new tapes. (CRP)
5. CORE ORIENTING TOOL
5.1 Pressure Transducer Housing design/build (ARP/EWB design, VUW MWkshp).
5.2 Pin impression type head, design/build (ARP/EWB design, VUW Mwkshp).
5.3 Software modifications (ARP/EWB)
6. CORE SPLITTING SAW
6.1 Modify core clamping rails to centre blade. (ARP, VUW Mwkshp).
6.2 Replace blade shafts with stainless steel bearings.
6.3 Purchase diamond saw blades @ 75 m/blade (ARP/CRP).page break
7. GPS SURVEYING
7.1 Y2K (486+) required for Community Base Station at Cape Roberts Hut.
7.2 Real Time Correction Signal - Compatible with any new Vehicle GPS units purchased and RTCM 104 compatable.
8. DRILLING
8.1 Down hole wire line cutters. Crimp and charge type for wire line.
8.2 Modify HQ fishing tool with HQ box? [tool was put in VUW cargo.]
8.3 Modify Bull Ring slips? [slips were put in VUW cargo.]
8.4 Van Routh plugs for cementing open hole sections to be drilled out later.
9. SCIENCE LABORATORY
9.1 Paper towels consumed @ 2 packs per 24 hours.
9.2 Core splitting blades, allow 80 m of drill hole each (10 × .065 × 5/8 inch).
9.3 Replace two hand pump garden sprayers (sea water corrosion and used for other purposes contaminated during decommissioning).
9.4 Four Lab-distinctive Tape Measures, 8 m quality/coated for better performance for sea water exposure.
9.5 Plastic core splits for boxed core. The core repository has requested that all core be boxed with splits.
